.edu backlinks are “supposed” to perform well in your link building strategy. And I think it makes sense because we know how difficult it is to get an edu backlink (meaning a backlink from a domain with .edu TLD).
Mostly .edu sites are universities or colleges and they only link to valid resources like wikipedia. So if someone linked to you, that would mean something.
Unfortunately, there’s been a lot of crowd sourcing happening in many .edu portals which has been exploited by SEOs, who paste links in the vain hope of getting some link juice. These projects normally are blogs/wikis etc.
In my opinion, links from an open wiki (with .edu domain) is as good as a normal wiki only. I mean if everyone pasted their links on the wiki, Google would treat is as spam right ? So what good is it ?
Anyway the post is not about spamming the edu wikis. For those who are curious about finding the edu links pointing to their websites, here’s the search query that’ll help you.
Go to Yahoo and search for this replacing with your domain name.
